Well, of course, we just need to clear out all that old mail that we received
but didn't send, and the universe will fall back into balance! ;)
.forward files still may point to heavy users, whether they read on Grex or
elsewhere.

If Grex gets that free T1 connection that has been discussed in a
different item, Grex would be able to hanlde a lot more electronic mail,
so this problem will not be as profound as it now seems. Before we take
any action, I suggest we see how things are if/after the T1 connection
is available. Another idea is to send the email-only users to M-Net.
Tell them that M-Net has a faster internet connection. This will kill
two birds with one stone, although quite nasty to M-Net. But hey, they
have a faster connection than Grex, and Grex often has more users logged
on than M-Net.
I think the idea of appending an automatic .signature file will not
work. It may advertise to others that Grex gives free E-Mail access to
anybody. But more importantly, it will have the opposite effect that we
want. If each E-Mail message is increased by "X" many bytes, then won't
that just cause Grex's connection to get slower from sending more data
over it's tiny 28.8 connection?
I doubt the idea of E-Mail quotas will work. If Grex downloads an
email address from a remote site, it would be quicker for Grex to just
give the user his or her email and be done with it. If email quotas are
implimented, then Grex would still have to receive the mail, but once it
is discovered that this person's mail quota is full (taking up processor
time) and then sending a message back to the foreign host (taking up
bandwidth) and then later receiving the message for a second time the
next day when the users' email quota is not full, which takes up even
more bandwith.
Perhaps the email survey is a good idea. I see one obvious problem
with it though. When the user ran the "newuser program" they probably
read the exact same information about the slow connection grex has, low
disk space, etc. What makes you think the user will all of a sudden
start caring about the needs of other people on Grex if they didn't
bother to follow the rules the first time, or even bother to reply to
the message? I doubt that this will provide good results, but it seems
like the best solution proposed so far.

I think the way our current mail quotas work (one MB per user mailbox size)
is by stopping the excess mail before it comes over the link.

There are certainly other places that "add" information to outgoing mail
or web pages. Personally, I don't like them. They are sort of like the
"obnoxicons" that show up in the lower right of your TV screen. Imagine
if, when placing outgoing phone calls, before you could speek, a
friendly recording showed up that said "this service provided by Ford
Motor Co, makers of fine automobiles."

Adding text to outgoing messages might cause some email-based
services to break. Consider mailing list software such as
listserv that expects commands to be one-line messages such as
"subscribe". It might be that they will work okay if extra text
is appended to the *end* of the messages, but I'm not sure.

Good point John--hadn't thought of that.
In general, I am against all the proposed systems to limit
e-mail, *except* that of informing the largest users.
Putting "limits" on email isn't going to work without changing
Grex drastically. We support an open newuser: therefore, the person
who doens't care about Grex and simple wants more email will take out extra
accounts, one for different types of email.
Back several months ago we stopped making a daily list of
disk usage statistics, and updating the "locate" database. While
technically prudent, it's been very bad in another sense because we
haven't been able to keep tabs on the system anywhere nearly as well
as before. I used to send messages out about twice a week to accounts
that were forwarding mailing lists, or using huge amounts of disk.
Nearly 99% of the people I sent mail to took care of the problem very
quickly, once they understood that there was a problem.
Before we make any new policies about email, I feel very strongly
that we should:
- make it muchmore clear at the front of newuser that Grex has
limits. Much more forceful unforunately. Longer, too.
- figure out ways to keep track of usage again, such that "problems" are
discovered soon after they have started up.
- change FTP such that smallish files go through the link very quickly,
but degrade at (100K? 150K?) some point making FTPs of mail
unattractive.
- send mail to the large users, explaining things to them.

(Most listservs seem to support a QUIT command, at least partly because of
.sigs that are automatically added & not under the user's control, I think.)

Would it take much coding to disallow .forwards? I use .forward myself but
if taking away a simple command line would help solve the mail problem. Also
havent seen any objections to earlier suggestion of restricting some of the
mailers (pine, elm .etc)

I object to restricting access to Pine and Elm. Come on, anyone
with half a clue will just port the code over and compile it themselves,
and if several users do that, it will slow the system down as much as
the mail flow does now.

Okay see...thats a reasonable reason why that suggestion is unworkable. I
accept that. Ofcourse Remmers would probably flame me for making the
suggestion in the first place because he only thinks certain users can
make valuable contributions to this conference.
I happen to thin that any contribution by anyone is valuable.

Depending on how it's used, .forward may actually help ease the
load on Grex. I forward all my Grex mail off-site and read and
reply to it on my own system. This means that some of my mail
travels over the internet link (a scarce resource) more times
than it would if I processed it on Grex, but on the other hand
it means that reading and replying to my Grex mail doesn't tie
up a Grex tty, pty, or the CPU (which are also scarce resources).

STeve -- Actually, we only turned off updating the locate database very
recently. I'm thinking about adding the "DiskUsage" stats but generating them
only once a week, maybe early on Sunday mornings, when usage is low. There's
a very recent disk-usage listing right now in /u/popcorn/du.home11.sorted,
if you're interested.
The problem with sending e-mail to heavy e-mail users is that
1) A lot of the time they get so much mail that your message is lost in the
deluge, and
2) Our heaviest mail users are often right at their Grex mail quota, so if
you try to send mail to them, it bounces because their mailbox is full. So
they never see the message.

#35...valid enough, restricting .forwards was just a thought. (contrary
to certain people's opinions, I do know when an issue should be dropped,
for instance I havent made a post in the "lets adopt mnet's confs" item
in weeks. Noone went for the idea. I droppped it. )

Right Valerie, but the DiskUsage stats showed me all sorts of things
that I'd have never expected it to, like sudden upsurges in disk use being
often an artifact of ah, "interesting" things that the person was doing.
Really, we need to get more net bandwidth, and monitor/tell large
(ab)users about what Grex is. I'd sure like to try those before we try
and figure out how to restirct things.

I've been doing some study of individual usage. It appears that "major users"
fall pretty much in two classes:
- Mailing list subscribers. Often just a single active mailing list is
enough
to put you near the top of the list.
- Huge files. Many of the people near the top of the list sent or recieved
just one or two very large files. I was sampling only a week's data, so
some of these people may be just one time members of the mail hog list. In
some cases, it looks like a single huge file got mailed into Grex, got
mailed from user to user, and then got mailed out again.
The first class of user could probably be productively talked to, suggesting
that they might consider subscribing to the mailing list from some other place,
if they have an alternative.
The second class is harder to talk to, because the people who were heavy users
one week may well not be the ones mailing around big files the next week.

I have some personal experience with heavy mail (ab)users. I live with one.
Here's what happened.
She is on a slow mailing list (probably average less than 2 messages per
day) and I have to remind her to get on grex to check her mail because I
sometimes check the size of her mailbox when I feel like it's been a long
time since she has logged in. I had to configure pine because she did not
often bother to delete old mail and her mailbox was getting full.
She gets on a more active mailing list that she really enjoys. She gets on
grex every day, sometimes more than once a day. She shouts at the computer
when grex crashes while she had been writing something. I try to get her to
compose messages off-line but the tools are hard to use and she wants to keep
doing it the way she knows.
I get tired of the phone being busy so much of the time because she's
composing mail on pine on grex.
I buy an account on a local ISP for us to share. I tell her to move the
mailing list stuff to the ISP account but she wants to keep doing what works.
I figure out how to subscribe the ISP account to the busy mailing list.
Soon she gets comfortable with the local mail tool and dialing the ISP.
When she is satisfied that everything works and is usable, I think I was
the one who had to unsubscribe the grex account to the mailing list.
She again has to be reminded to get on grex to check the slower mailing
list. She prefers to send mail from the ISP, so she will forward any mail
from grex to the ISP if it needs a reply.
She wants a .forward from grex to the ISP account, but I tell her that she
should not do that while the grex account is on a mailing list. She does
not bother to figure out how to get the slower mailing list to switch
over. Eventually I take care of that and set up the .forward.
Finally, her .forward generates very little traffic, and she does not have
to get on grex to read mail.
So, why did I type all that? I'm not trying to insult her. I'm just
trying to say that some of the mail abuse may be coming from people who
don't know any better and maybe we have to make the effort to help them
set up in an efficient way which minimizes the impact on grex.

Kaplan, does staf have an official policy saying users cant
.forward mailing lists? I was only aware that originating
mailing lists is a no-no on grex.

For small volumes, we're not that likely to notice. When somebody is
forwarding a large volume of stuff through Grex, we generally send them mail
asking htem to please not do it.

Right, I didn't say she couldn't have a .forward file because of the mailing
list. I just said I didn't think she should have one.

There are several low-volume mailing lsits on Grex right now. In
each case, I talked to the person behind it, found out that is really
was low, and made them promise to keep it that way. All those people
that; I think the number is four at this time.
What we usually see however, is someone who blithly ignores the
comments in newuser, and creates a .forward file with 20+ people on
it. The largest .forward I found had about 80 people on it.

Actually, it's fairly recent that newuser asked people not to create mailing
lists on Grex. For some reason we forgot to list that. I added text about
mailing lists maybe a month or three ago. And I think the number of mailing
lists we've run across since then has been much lower.

just one thought .. i agree that adding something (obnoxicons) to the
tail fo the email (obnoxicons ... heh, nice) has some boorish qualities
associated .. however, it is the *location* that retains that quality.
it is more feasible, i think, while achieving the same goal (not boorish)
to put s single line in the *header* that says approx the same thing,
or, alter some current line in the header with the significant information.
